2-(4-Fluoro-2-nitrophenyl)-4-hydroxy-9-phenylsulfonyl-9H-carbazole-3- carbaldehyde

Abstract

In the title compound, C25H15FN2O 6S, the carbazole ring system is essentially planar, with a maximum deviation of 0.1534 (16) Å for the C atom connected to the 4-fluoro-2-nitrophenyl ring. It is almost orthogonal to the phenylsulfonyl and nitrophenyl rings, making dihedral angles of 88.45 (8) and 79.26 (7)°, respectively. The molecular structure is stabilized by O - H⋯O and C - H⋯O hydrogen bonds, which generate three S(6) ring motifs. In the crystal, molecules are linked by two C - H⋯O hydrogen bonds, which generate C(6) and C(9) chains running in the [100] and [010] directions, respectively, so forming a two-dimensional network lying parallel to (001). There are also supramolecular R 4 3(28) graph-set ring motifs enclosed within these networks.
